{\mathbb{CORRECT...ANSWER}}

✔The stress–energy tensor, sometimes stress–energy–momentum tensor or energy–momentum tensor, is a tensorquantity in physics that describes the densityand flux of energy and momentum in spacetime, generalizing the stress tensor of Newtonian physics. It is an attribute of matter, radiation, and non-gravitational force fields.
